Use Multilanguage Neural Voice

[ovbm]

The Neural Voice "Jenny" supports German, French, Italian and English. We could replace the current one with Jenny and A) us dictionaries to auto-tag words that aren't german and B) enable production to alter the language of individual words.

Example SSML:

<voice name="en-US-JennyMultilingualNeural">
  <prosody rate="0%" pitch="0%">
     <lang xml:lang="de-DE">Bundespräsident</lang><lang xml:lang="fr-FR">Alain Berset</lang> <lang xml:lang="de-DE">ist am</lang> <lang xml:lang="en-US"> world economic forum</lang>.
  </prosody>
</voice>
